Refrigerated Groat Jars Set Of 2

Simons Maison's Refrigerated Groat Jars Set Of 2 pairs premium borosilicate glass bodies with polypropylene lids and dishwasher-safe silicone seals, delivering thermal shock resistance for freezer-to-microwave transitions and leakproof shake mixing at $7.50 per jar — half the cost of comparable containers. Designed with a wide 3.3-inch mouth and squat 4.75-inch height, the 500 ml jars fit fridge doors and lunch bags, supporting weekly meal-prep rotations. Backed by a 180-year family-run Quebec retailer, these jars offer entry-level pricing for durable, stain-resistant materials, making them ideal for overnight oats and cold storage despite a specialized focus on groats.

Price per jar

Each jar costs $7.50 — half the typical $12–20 for comparable borosilicate containers.

Why this is supported

At $7.50 per jar, this set undercuts the $12–20 typical for national-brand borosilicate containers.

this set's $7.50-per-jar price effectively delivers a premium material at entry-level pricing — the same cost often buys only a basic soda-lime jar with a snap-on lid.How this set compares to similar glass jar sets — borosilicate_glass_at_soda_lime_pricing

The watertight silicone seal is a premium feature often found on $20+ containers, included here.

the lid is described as watertight with a silicone seal, making it leak-proof for carrying liquids like soup or smoothies in a bag.Are the lids truly leak-proof for carrying liquids like soup or smoothies in a bag?

The set-of-two format enhances value with a continuous meal-prep rotation.

Having two jars supports a weekly meal-prep cycle where one jar soaks overnight while the other is used elsewhere, so you never have to wash and immediately refill a single containerWhy the size and seal matter for chilled groats — set_of_2_enables_grab_and_go_rotation

Material

80% borosilicate glass body with polypropylene lid — thermal shock and stain resistant, unlike soda-lime jars.

Why this is supported

The borosilicate glass body (80%) with polypropylene lid offers thermal shock resistance and durability against stains, odors, and scratches, unlike common soda-lime glass.

Borosilicate glass has a linear expansion coefficient of ~3.3 × 10⁻⁶ /°C — roughly one-third that of soda-lime glass — so the jar mouth stays dimensionally stable during freezer-to-microwave transitions, meaning the silicone gasket doesn't have to flex to maintain a seal, reducing mechanical fatigue and extending gasket life.Keeping the watertight seal effective over time — borosilicate_silicone_thermal_expansion_synergy

The silicone gasket withstands dishwasher sani-cycle temperatures and high heat without degradation, and the lid assembly is dishwasher safe.

The polypropylene lid and silicone gasket are both dishwasher safe — unlike lids on some budget food storage that warp or lose their seal after repeated machine washesWhat to expect from Simons Maison kitchenware — dishwasher_rated_lid_assembly

Design for use

Wide 3.3-inch mouth and squat 4.75-inch height — ideal for overnight oats and fits fridge door and lunch bag.

Why this is supported

The wide 3.3-inch mouth and leakproof seal make these jars ideal for overnight oats and shaking.

The watertight silicone seal allows you to mix groats by shaking the sealed jar vigorously without leaking, a time-saving step that skips the need for a separate bowl and spoon before the soak — something many decorative or insulated jars cannot guaranteeWhy the size and seal matter for chilled groats — silicone_sealed_polypropylene_lid_for_shake_mixing

The squat 4.75-inch profile fits refrigerator door racks and lunch bags, and borosilicate glass allows direct freezer-to-microwave use.

Standing under 5 inches tall, the jar fits in refrigerator door racks and standard lunch bags, and its low center of gravity reduces the chance of tipping on uneven surfaces while stirring or eating directly from the container.Why the size and seal matter for chilled groats — short_squat_profile_at_4_75_inches_high

you can safely pour boiling water directly into a frozen jar to warm groats or move it from freezer to a hot water bath without risk of shattering — a flexibility that generic glass storage jars cannot provide.Why the size and seal matter for chilled groats — borosilicate_glass_thermal_shock_resistance

Thermal performance

Low thermal expansion enables safe freezer-to-microwave transitions and extends seal lifespan.

Why this is supported

The low thermal expansion coefficient

lets it endure rapid temperature swings, so you can safely pour boiling water directly into a frozen jar to warm groats or move it from freezer to a hot water bath without risk of shatteringWhy the size and seal matter for chilled groats — borosilicate_glass_thermal_shock_resistance

. This dimensional stability also benefits the seal:

Thermal shock

Withstands freezer-to-microwave, boiling water into frozen jars, and hot dishwasher cycles.

Why this is supported

The borosilicate glass in these jars has a thermal expansion coefficient roughly one-third that of soda-lime glass, enabling safe direct transitions:

Yes, the jars are made from durable borosilicate glass and are labeled both freezer and microwave safe, so they can go directly from the freezer to the microwave without risk of thermal shock.Can the jars go directly from the freezer to the microwave without thermal shock?

Beyond this, the same property permits more aggressive heating:

Unlike standard glass, borosilicate glass has a low thermal expansion coefficient that lets it endure rapid temperature swings, so you can safely pour boiling water directly into a frozen jar to warm groats or move it from freezer to a hot water bath without risk of shatteringWhy the size and seal matter for chilled groats — borosilicate_glass_thermal_shock_resistance

and the resistance to thermal cycling also reduces stress fractures from dishwashers, as the research notes:

Borosilicate glass has a thermal expansion coefficient roughly one-third that of soda-lime glass, giving these jars superior resistance to thermal shock — they can go from freezer to microwave without cracking, and that same low-expansion property reduces the formation of stress fractures from repeated hot dishwasher cycles, extending usable life well beyond typical glass storage.What to expect from Simons Maison kitchenware — borosilicate_glass

Size

3.3-inch mouth, 4.75-inch height, 500 ml capacity — ideal for overnight groats and fridge storage.

Why this is supported

The jar’s dimensions are engineered for overnight groats:

The jar's 3.3-inch diameter and 4.75-inch height yield roughly 16 fluid ouncesWhy the size and seal matter for chilled groats — 500_ml_single_serve_volume_from_dimensions

, leaving headspace for stirring and additions. The wide mouth simplifies assembly:

A 3.3-inch opening is broad enough to fit an adult spoon and allows layered toppingsWhy the size and seal matter for chilled groats — wide_3_3_inch_mouth

. The squat height adds storage convenience:

Standing under 5 inches tall, the jar fits in refrigerator door racks and standard lunch bagsWhy the size and seal matter for chilled groats — short_squat_profile_at_4_75_inches_high

. These specifications together verify that the 3.3-inch mouth, 4.75-inch height, and 500 ml capacity align with overnight groat preparation needs.

Dishwasher durability

Dishwasher-rated lid and gasket maintain watertight seal after repeated cycles.

Why this is supported

Catalog verified that the lid assembly is designed for component-level durability rather than just initial leak-proofness:

a design signal that the brand prioritizes component-level durability rather than just initial leak-proofnessWhat to expect from Simons Maison kitchenware — dishwasher_rated_lid_assembly

The polypropylene lid resists warping, and the silicone gasket withstands heat up to 70°C. The borosilicate glass's dimensional stability further reduces gasket fatigue, while the food-grade silicone resists chemical attack from acids in typical overnight groat recipes. A periodic vinegar or baking soda soak can restore the seal's grip and neutral scent over years of use. The lid is BPA-free, so repeated heating does not pose safety concerns.
